Alumina refining porous plug made by composite materials sintered at high temperature. It characterized by dispersive porous mode, erosion resistant, metal non-wetting, molten alumina non-infiltrating, can effectively remove impurities from molten alumina, prevent molten alumina hydrogenation and oxidation, reduce the burning loss of molten alumina, and improve the melting efficiency.
The Series of aluminum groove, distribution channel, filter box, Degassing tank , burner, mixing head, reflecting furnace door frame, vortex well, the whole lining and other non wetting aluminum unshaped precast brick, is the use of non wetting aluminum castable to casting and after high temperature heat treatment process.
High strength metal non-wetting castable are ultra low cement castable , especially designed to alumina and alloy indsutry ,with high density , high strength and insualaion aluminum and alloy solution , can significantly reduce the corundum abnormal growth and molten metal penetration.
Boron nitride coating materials are widely used on the surface for chute ,shunt plate , launder , casting platform lining , filter box , adapter palte , casting tip and son on .
